How words are pronounced can be found in the lessons (including spoken samples), here.

As for finding words, the translator can often help. You could also go through the dictionary page by page and find it by ctrl+f, but that's very inefficient. The search option can help as well.

Keep in mind that there are plenty of words Dovahzul doesn't have; you can submit your own words too, if you think a word is missing.

Su'um ahrk morah, and good luck!
